Thanks.  I think it may be the -DNO_GZIP was -DNO_GUNZIP at some point
or somehow NO_GUNZIP got defined.  inffas86.c is using the TYPE and BAD
enums from inflate.h which change value with -DNO_GZIP, but inffast.S
has an #ifdef NO_GUNZIP for those enum changes.  I'll check to see if
that's what is causing it... defining -DNO_GUNZIP as well as -DNO_GZIP
should do it.
